Cryostasis Glitch or Bug??

[wiss83]

Hey everyone!
putting all the game's problem aside, Cryostasis is a really great game!
but I'm having some issues, and hope someone could help me!
I'm now in the 2nd flashback of the diver, I did cut the pipe, and a big current drag me, now I can see a zombie (or whatever it is) hitting my suit with an axe till he brakes the glass. now the thing is that I have to pick up the axe and help my friend cause the zombie starts attacking him
and that's where the problem is
when the zombie hits me with the axe and leave it to attack my friend, the axe just disappears and I can't move my hands or do anything!!!
so I'm just stuck watching my friend dying and loosing this level, to return back and repeat it with the same thing!
sorry for the long thread! but I'm desperate for some help.
Thank you
